Title:
HEAT EXCHANGER AND HOT-WATER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/038568
Kind Code:
A1
Abstract:
A defrosting heat exchanger (19) is provided with low-pressure refrigerant piping (20) in which a low-pressure refrigerant flows, high-pressure refrigerant piping (21) which is wound around the low-pressure refrigerant piping (20) and in which a high-pressure refrigerant flows, and water piping (56) which is wound around the low-pressure refrigerant piping (20) and in which water flows. The low-pressure refrigerant absorbs heat of the high-pressure refrigerant and the water, and this raises the temperature of the low-pressure refrigerant. Heat of the high-pressure refrigerant and the water is absorbed by the low-pressure refrigerant, and this lowers the temperature of the high-pressure refrigerant and the water.
